Improving the efficiency of Liquid Air Energy Storage by organic rankine cycle module application

Abstract

In the paper The Liquid Air Energy Storage (LAES) technology is described. The LAES can be constructed in every place, bases on well-known components and is dedicated for system scale and short-term energy storage. The most important issue is to increase the energy storage efficiency and its economic attractiveness. For that purpose the Organic Rankine Cycle application was proposed. The new variant of the Liquid Air Energy Storage with Organic Rankine Cycle (LAES-ORC) was developed, including technical analysis, the mathematical model implementation description, simulation results and its analysis.
